Question

我需要这个应用来做一个简单的点击计数器这里是我的MainAvtivity的java脚本。我设置了一个Button和TextView，但出于某种原因，当我在我的模拟器上运行它时，按下按钮时没有任何反应。如果有人有时间陪伴我，我愿意给你我的电子邮件地址。请帮忙:(

这是MainActivity：

package com.example.myfirstapp;

import android.support.v7.app.ActionBarActivity;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.TextView;

public class MainActivity extends ActionBarActivity {



int TextView = 0;
TextView text;

public void count1(View v){
    Button button = (Button) findViewById(R.id.button);
    text = (TextView) findViewById(R.id.text);
    button.setOnClickListener(new View.OnClickListener(){
        @Override
        public void onClick(View v){
            // TODO Auto-generated method stub

            TextView++;
            text("count " + TextView);

        }
    });


}



protected void text(String string) {
    // TODO Auto-generated method stub

}



@Override
public boolean onCreateOptionsMenu(Menu menu) {

    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}

/**
 * A placeholder fragment containing a simple view.
 */
public static class PlaceholderFragment extends Fragment {



    public PlaceholderFragment() {
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_main, container, false);
        return rootView;
    }
}

 }

也许试试：

text.setText("Count " + TextView);
